集合A={x|y=
|
答案
由集合A中的函数y=
，得到x≤2，2-x
所以集合A={x|x≤2}；
由集合B中的函数y=x2+1≥1，得到集合A=[1，+∞），
则A∩B={x|1≤x≤2}．
故选B．

第Ⅱ卷（非选择题 共35分） 第四部分写作(共两节，满分35分) 第一节：任务型读写(共10小题；每小题1分，满分10分)阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。 Some people succeed, while others may not. This is because some people possess certain qualities, which others do not. The first thing you must remember is that in order to succeed, you must be optimistic. If you do not expect to win, you will not try as hard as those who do expect to win. You also need to have a clear aim and a reason for doing something because motivation is a key to achieving success. If you do not have an aim, you will not be motivated to work hard put your performance under the microscope to make sure that every detail is right. Another quality that helps people succeed is creativity-----thinking about things in a different way and wondering how others would do the same thing. Think about some successful people you know. They might be successful with a little creativity, but the most successful people are the most creative ones. Reading is another to success, as it will help you learn about how other people have achieved success. If you want to learn how to set up a successful business, you should read books about famous people like Bill Gates and Jerry Yang, who have achieved amazing success in their areas of business. Practicing is equally important if you want to succeed because practice makes perfect. Practice every day at whatever career you are in, and by doing so, you will see yourself, your business and your self-confidence begin to grow. If you feel confident about what you do, this confidence will make other people believe in you as well. Your colleagues will be happy to work with you, and your boss will give you more responsibility. Finally if you are a successful person, you will be able to look people in the eye and smile confidently. Success is yours for the taking! Cheers!
